In 1994, the U.S. government held a lottery to issue 55,000 Green Cards (permits for non-citizens to work legally in the U.S.). Renate Deutsch, from Germany, was one of approximately 6.5 million people who entered this lottery. Let G = won Green Card. Part (a) What was Renate's chance of winning a Green Card? Write your answer as a probability statement. (Round your answer to four decimal places.) P = Part (b) In the summer of 1994, Renate received...

True or False With explanation please.
e. If two events are mutually exclusive, they are àl f. The mean of a discrete random variable X is penide found by multiplying each possible value of X by its own probability and then adding all the products together; that is XPO g. Two events A and B are said to be independent if P(A and B)y- PIA)-P(B) h. Assume that X is a normally distributed random variable with a mean ofμ and...
